Bought the Shockwave to upgrade from the spitfire. Get the better sound different options and more calls. Works great called in a lot of dogs so far. Still got more features that I haven't had time to mess with yet.
Two downfalls I do see with this unit so far. Battery life is a lot less than what I expected . So carry extras..
#2 the Fox Bang feature seems to activate on its own when not needed.
It does have adjustable sensitivity. But even on Lowest sensitivity it's still activated sometimes. When fumbling with the Remote if you bump it on your stock or put it in your pocket and hit something that sound alone will trigger it.
Other than that no complaints. Great call!
